My read is that he is contemplating his lies and does not wish to be caught. I seldom lie, because I do not think I am so clever that I will remember the story. Speaking from the heart takes no such contemplation, but it just flows, like Rubio's speech about why he is with the Conservatives. Remember, Obama has disappointed his Leftist associates by not moving fast enough to their goals. Watch for references of progress to yet be made. It is progress towards the goals of Jeremiah Wright and Bill Ayres, although which ever get the upper hand, they would go after each other. His listeners will think he is talking about progress toward prosperity for all Americans. Not so.
